INSTRUMENT FOR RENIOVING OBSTRUCTIONS FROM PIPES.

SPECIFICATION forming part f Letters Patent No. 558,549, dated April 21,1896. Application led January 5,1895E Renewed Marchrll, 1896. Serial No.582,825. (No model.)

To all whom t may concern,.-

Be it known that I, WILLIAM C. DILLMAN, a citizen of the United States,and a resident of the city of Brooklyn, in the State of New York, haveinvented new and useful Improvements in Instruments for RemovingObstructions from Pipes, of which the following is a specification.

The object of my invention is to provide an ro improved instrument forremoving obstructions from pipes, and is especially designed for use incases where obstructions occur in pipes that are curved or bent or haveelbowsas, for instance, in clearing the soil-pipe of a I5 water-closetor the waste-pipe of a sink.

I have in the accompanying specification and drawings illustrated myinvention as applied to removing all obstructions in the soilpipe of anordinary water-closet, but it is obzo vious that it can be applied in avariety of other cases when obstructions have to be removed from pipes.

In the accompanying drawings, Figure 1 is a sectional elevation. Fig. 2is a plan view,

2 5 partly in section. Fig. Sis a section of a water-closet soil-pipe,showing my instrument inserted. Fig. 4 is an elevation showing amodilied form of one of the features of my invention, as hereinafterdescribed.

3o In the above drawings, A is a handle of any suitable length,consisting of a rigid rod a and a suitable device a for grasping sameand connected at its lower extremity with a sectional stem E.

3 5 B is a stem formed of separate sections b Z), made preferably ofthin stamped iron plates, linked and pivoted together, as shown, so asto allow free lateral movement of the sections of which it is composed.

4o C C are a pair of curved and pointed jaws attached to the end of thesectional stem B and havinga diameter when extended slightly less thanthe diameter of the pipe to be operated on. The shape and size of thesejaws may be varied to suit the various obstructions required to beremoved, and for this purpose I secure them to the stem B by anysuitable detachable device, so that jaws of varying size and shape canbe used on the same stem.

rwhen the chain or string attached to such toggle-joint is tightened.

E is a chain or string connected with and operating the toggle-joint eand passing through the rings or screw-eyes f f, attached to the 6o stemB.

F is a spring by whichthe jaws c c are kept normally expanded.

Gis a flexible sheath, made preferably of vulcanized-rubber tubing,stretched over and inclosing the stem B for facilitating the passage ofsuch stem through a curved pipe K by controlling and regulating thelateral movements of the sections b b and preventing them jammingagainst the curves or elbows of such 7o pipe.

In Fig. 4 I show a modification of my instrument, in which in some casesI dispense with the eyes ff and the chain E and substitute a differentmode of closing the jaws C C. In this figure, H is a frame of theordinary lazy-tongs type composed of strips or bars pivoted together atthe points c, two of such bars being affixed to the ends of the jaws C Oin the ordinary way and two other bars be- 8o ing pivoted to the stem Bby a detachable pivot or other removable fastening.

In applying my invention the stem B is pushed down the pipe K by thehandle A, the jaws C O being kept extended by the spring F till theobstruction is reached, when the jaws C C are closed on such obstructionby tightening the chain E, which operates the toggle-joint, or by theaction of the lazy-ton gs I-I, and the instrument is withdrawn. 9o

The jaws C C may be made of various shapes to suit dierent kinds ofobstructions but in every case the operation of the parts of myinstrument is to cause such jaws to remain wide open when the instrumentis being pushed down the pipe and to close such jaws tightly when theinstrument is being withdrawn.

through the rings or screw-eyes f. f. attached to the stem B to thehandle A, substantially as described and for the purposes specified.

In testimony that I claim the foregoing as my invention I have signed myname, in presence of two Witnesses, this 14th day of December, 189i.
